EGITNOPERMISSION error if trailing .git is missing from repository URL

[pvdlg]

In certain cases, apparently with GitHub and Travis, if the repository URL doesn't end with .git the command git push --dry-run <repositoryUrl> HEAD:<branch> fails and semantic-release errors out with EGITNOPERMISSION.

It's not really clear under which circumstances the issue happens.

See #771 for an example of the problem.
However it doesn't happen in this test: https://travis-ci.org/pvdlg/test-sr/jobs/374590162#L443

We would need to figure out in which circumstances (GitHub repo config, Travis image, Git version, etc...) a URL without .git fails. Depending on the finding we would add the .git to the URL in such circumstances or we would write a FAQ or troubleshooting section explaining the findings.

The .git is not added automatically as some Git host, such as VSTS doesn't work with it. It's not really clear when it is required or not, so for now semantic-release keep it if it's set by the user in the package.json or in the repositoryUrl and doesn't added if it's missing.

I was getting this error in VSTS so I changed to ssh authentication and it stops.

Old url:

"url": "https://xxxxxx.visualstudio.com/xxxxx/_git/xxxx"

New one:

"url": "ssh://xxxx@vs-ssh.visualstudio.com:22/_ssh/xxxxx"

Closing as the problem doesn't seems to happen anymore
